The 1910 census does not include the family. Arthur is listed on a supplemental page but the rest of the family do not appear even in the section covering the house number and address. It is possible they were still in Illinois but they cannot be found there in the census either.

Note

The following are from the business directories of Guthrie, Logan Co., OK. It would appear that Arthur might have gone there before his family and started a business. There was not another A. Humphrey in Guthrie during that period. SInce his father was already there, it seems plausible he went there for a while. Perhaps they returned to Illinois in 1900 and returned.
